Most people said MariaDB better then old MySQL Server, so i decided to migrate Database Server from old MySQL to new MariaDB Server
For brief info MariaDB is a community-developed fork of the MySQL relational database management system intended to remain free under the GNU GPL. It is notable for being led by the original developers of MySQL, who forked it due to concerns over its acquisition by Oracle.
